STATEMENT ON MALAYSIAN FLIGHT MH 17

Friday, July 18, 2014

The International AIDS Society (IAS) today expresses its sincere sadness at receiving news that a number of colleagues and friends en route to attend the 20th International AIDS Conference taking place in Melbourne, Australia, were on board the Malaysian Airlines MH17 flight that has crashed over Ukraine earlier today.

At this incredibly sad and sensitive time the IAS stands with our international family and sends condolences to the loved ones of those who have been lost to this tragedy.

27. Australia’s foreign minister, Julie Bishop, has held a press conference in Brisbane. She’s called for Australian staff to get access to the site.

She speculated that the reasons so many Australians died in the crash was due to it being a common connecting flight between Amsterdam-Kuala Lumpur-Perth.

There’s also been confirmation many on board the flight were heading to a World AIDS Conference in Melbourne to start next week.

28. It’s not the only event involving Australians overseas this morning. Ms Bishop has confirmed that an Australian suicide bomber has been involved in an incident in Baghdad where at least three people have been killed.

29. The comments came after Mr Abbott blamed the crash on the activities of Russian president Vladimir Putin.

Australian PM Tony Abbott on #MH17 tragedy - "This is only happening because Russia wants to stir up trouble"

“It seems there were at least 23 Australians on this flight. Obviously the Department of Foreign Affairs is talking to Dutch authorities to confirm numbers and identities but it does seem there were definitely 23 Australians on this flight.

“We can assure families that, at the highest levels of government, we feel for them, we grieve with them and we pray for them. That’s the first thing we go. The second thing is to try to provide whatever practical assistance we can, in terms of counsel and the repatriations of remains and so on.

“This tragedy is made worse by reports it might be a crime rather than an accident. Let’s wait until we’ve got all the facts in … but obviously it is the clear and settled position of the Australian government that larger countries should not bully smaller ones, that countries should not aide people in rebelling against their own government and that disputes between nations should be settled peacefully and under international law.

“We just have all sorts of reports and claims flying around, that’s all we have at the moment.

“If it does turn out that this aircraft was brought down by a surface-to-air missile, this would be an unspeakable crime.”
